Chemopreventive agents in black raspberries identified
January 08, 2009PHILADELPHIA - A study published in Cancer Prevention Research, a journal of the American Association for Cancer Research, identifies components of black raspberries with chemopreventive potential.
Researchers at the Ohio State Comprehensive Cancer Center found that anthocyanins, a class of flavonoids in black raspberries, inhibited growth and stimulated apoptosis in the esophagus of rats treated with an esophageal carcinogen.
"Our data provide strong evidence that anthocyanins are important for cancer prevention," said the study's lead author, Gary D. Stoner, Ph.D., a professor in the department of internal medicine at Ohio State University.
Stoner and his team of researchers fed rats an anthocyanin-rich extract of black raspberries and found that the extract was nearly as effective in preventing esophageal cancer in rats as whole black raspberries containing the same concentration of anthocyanins. This study demonstrates the importance of anthocyanins as preventive agents in black raspberries and validated similar in vitro findings. It is among the first to look at the correlation between anthocyanins and cancer prevention in vivo.
Stoner and his colleagues have conducted clinical trials using whole berry powder, which has yielded some promising results, but required patients to take up to 60 grams of powder a day. "Now that we know the anthocyanins in berries are almost as active as whole berries themselves, we hope to be able to prevent cancer in humans using a standardized mixture of anthocyanins," said Stoner.
"The goal is to potentially replace whole berry powder with its active components and then figure out better ways to deliver these components to tissues, to increase their uptake and effectiveness. Ultimately, we hope to test the anthocyanins for effectiveness in multiple organ sites in humans," said Stoner.

Anthocyanins: Biosynthesis, Functions, and Applications by Kevin Gould (Editor), Kevin Davies (Editor), Chris Winefield (Editor) In recent years there has been an unprecedented expansion of knowledge about anthocyanins pigments. Indeed, the molecular genetic control of anthocyanins biosynthesis is now one of the best understood of all secondary metabolic pathways. There have also been substantial improvements in analytical technology that have led to the discovery of novel anthocyanin compounds. Armed with this knowledge and the tools for genetic engineering, plant breeders are now introducing vibrant new colors into horticultural crops. The food industry has also benefited from the resurgence of interest in anthocyanins. A greater understanding of the chemistry of these pigments has led to improved methods for stabilizing the color of anthocyanins extracts, so that they are more useful as food colorings. Methods... |

Black Cherry Concentrate, Dynamic Health, 16 oz by Dynamic Health Cherries have pleased the palates of food lovers for centuries. Now there are new reasons to love cherries. As a recent Newsweek article said "The day when doctors say - 'Take 10 cherries and call me in the morning' - may not be far off." According to ongoing research, cherries are a rich source of antioxidants that can help maintain heart health, joint health and blood circulation. The secret is in the pigments that give cherries their rich red / black hue. They belong to a class of natural dyes called anthocyanins. These compounds are being called "Mother Nature's all-natural chemotherapy agents." In addition to the antioxidants, cherries are rich in two important flavonoids - isoqueritrin and queritrin. According to leading researchers, queritrin is one of the most potent agents... |

Anthocyanins as Flower Pigments: Feasibilities for Flower Colour Modification by T. Mulder-Krieger (Author), R. Verpoorte (Author) The economic value of cut flowers is considerable. Because novelty is a driving force in this section of horticulture, the development of new flower varieties is of great interest. In this connection new colours are particularly important. Classical plant breeding has been able to produce a broad variety of colours and forms for flowers but with the tools for genetic engineering available, a new era for cut flower plant breeding has dawned. The present study reviews the various aspects connected with the molecular engineering of flower colours. The resuls achieved so far, bottlenecks and possible approaches in altering flower colours are discussed. The methods available for genetic modification of plants are briefly reviewed. This study concentrates on the anthocyanins. The biosynthetic... |
